47-353 25.0mm Dia. x 175.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
This is a 25.0mm diameter, 175.0mm focal length plano-convex lens, designed for use in the visible light spectrum (425-675nm). The lens is sourced from Edmund Optics, a leading provider of optical components.
The lens is made from n-BK7 Schott glass, a popular material for its high refractive index and low dispersion. This makes it ideal for applications that require high image quality and minimal chromatic aberration.
The plano-convex design features a flat front surface and a curved back surface, with a radius of curvature of 90.47mm. This design is often used in optical systems where a large, collimated beam needs to be focused to a small spot.
The lens features a standard anti-reflective coating on both the front and back surfaces, designed for use at normal incidence in the visible spectrum (VIS 0°). This coating reduces surface reflections, improving transmission and reducing ghosting and flare.
The lens has an edge thickness of 2.63mm and a center thickness of 3.5mm. The back focal length is 172.85mm, and the effective focal length is 175mm. The lens has no inner or outer radius, indicating a uniform thickness.
